Man who disarmed Monterey Park shooter speaks out: 'Something came over me'

The night was winding down after a Lunar Near Year celebration at the Lai Lai Ballroom & Studio in Alhambra, California, on Saturday, when Brandon Tsay heard the front

door click close behind him. "That's when I turned around and saw that there was an Asian man holding a gun. My first thought was I was going to die here, this is it,"

Tsay, 26, told ABC News' Robin Roberts during an interview Monday on "Good Morning America."MORE: Monterey Park mass shooting live updates Tsay, who helps run the dance

hall with his family, said the gunman was "looking around the room" as if he was "looking for targets -- people to harm." "He started prepping the weapon and something

came over me," Tsay recalled. "I realized I needed to get the weapon away from him. I needed to take this weapon, disarm him or else everybody would have died." "When I

got the courage, I lunged at him with both my hands, grabbed the weapon and we had a struggle," he added. "We struggled into the lobby, trying to get this gun away from each

other. He was hitting me across the face, bashing the back of my head." Tsay said he used his elbows to separate the gun from the suspect during the struggle until,

finally, he was able to pull the weapon away and shove the man aside. Tsay said he then pointed the gun at the suspect and shouted: "Get the hell out of here! I'll shoot! Get

away! Go!" "I thought he would run away, but he was just standing there contemplating whether to fight or to run," Tsay recalled. "I really thought I would have to shoot

him and he came at me. This is when he turned around and walked out the door, jogged back to his van. I immediately called police with the gun still in my hand."
